Abstract (en)
[origin: WO03099540A1] A clad tube (21) is formed by melting and extruding a polymer, such as PMMA. The molten polymer is extruded through an extrusion die (12) to form a soft clad (20). The soft clad (20) is forwarded to a molding die (13) to correct the shape of the soft clad (20). A decompression chamber (31) in the molding die (13) is decompressed so that the outer surface of the soft clad (20) is tightly in contact with forming surface (30b) of the molding die (13). After molding the soft clad (20) in the molding die (13), the clad tube (20) with low fluctuation in thickness is obtained.
